MC: is pretty much the only nice one(unless you count choices that the player makes, then he can be horrible)
Didac: just horny ALL the bloody time
Neus: she was so unwilling to make the first move on MC that she uses a kidnapped(by her) child to do a demonic/satanic ritual to have enough energy to do the "didac wants to rape Neus" and the "didac is now a girl" spells. Not to count how she took part in Satan(her dad)'s rituals until she decided "these rituals are evil, i quit"
Txell: she openly says that the thing she likes the most is to fuck-up with people's minds with her words, imagine a therapist that wants you miserable because she enjoys being manipulative, but the second someone calls her out or refuse to think how she wants them to think, she throws tantrums like a child(in one of the routes, MC can kill her and Neus hates you for that, despite....being Neus), and yes Txell was a past girlfriend of Neus and she hates you because Neus is more focused on you now(her own twin brother btw)
